    A Unit of Luminous Intensity, or brightness. From http://physics.nist.gov/cuu/Units/candela.html :
    See also lumen, Foot-candle.

    On spec sheets for luminaires, BCP is usually expressed in peak candelas, and performance at any distance may be calculated using the formula
    intensity in FootCandles = BCP/distance^2.
